Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

The contact stated when turning a corner or driving over a bump heard a loud noise. It sounded as though metal was rubbing together. This happened when she drove the vehicle off of the lot. The vehicle has been to the dealership multiple times. They replaced the front suspension sway bar and front control arm six times, and had to be replaced every six months or 3,000 miles. The vehicle was still experiencing the same problems. Updated 12/27/2005.

2003 Chevrolet trailblazer - purchased in may of 2003 off of the sales floor - around 5 miles on it - truck began squeaking - took it in, they said bad break pads, changed them out and gave it back (2 days without truck) - squeaking still there - took it back in - service tech said the front spindle was bent - told me I couldn't drive it it was unsafe (5 more days without truck) - at the same time they take truck to body shop because rear hatch won't shut it too is bent - same with the hood (hmmmmmmmm!!!!) - rear wiper motor then busts (now I'm erked) - driving down the highway at 55 and truck shuts off - no power steering almost wreck it seems the gas gauge is not accurate!!!!!!! - then blower motor won't shut off without taking fuse out... no heat in rear heaters, climate control doesn't work (yet a few more days without truck)- the last straw - my 9 month old truck has a broken transfer case and the 4-wheel drive went out - of course the 4-wheel drive went out on a steep hill in the middle of winter - not acceptable in Alaska not acceptable in a new truck!!!!!! - had to get out of a defective truck so now we are stuck with a brand new Tahoe that is $10,000+ upside down! you decide who is wrong in this case!
